New Revision: 150198

URL: http://svn.digium.com/view/asterisk?view=rev&rev=150198
Log:
Fix a memory leak added in my last commit when using ast_asprintf.
Attribute 'name' in a <parameter> tag is required, so it is not needed to continue parsing the <parameter> if
no 'name' was given.
Cleanup the code (style).
